论柏拉图《法律篇》中"法治范式"的当代启思

“法治”是柏拉图《法律篇》中所倡导的“混合政治”的核心内涵,是一种将君主制的君主原则与民主制的民主原则相融合的新型的“法治范式”。文章在剖析柏拉图“法治”思想的基础上,详细地阐述了柏拉图法治思维对当代中国政治转型的思维启发价值。     

ASSESSING THE RELATIONSHIP BETWEEN SYMPTOMS OF ALLERGIC RHINOCONJUNCTIVITIS AND POLLEN COUNTS

The relationship between daily pollen counts during the peak pollen season and hay fever symptoms in known sufferers of pollen allergy was investigated in a Sydney hospital‐based study. This paper develops statistical models for both the short term (day to day) associations and the longer term relationships between these time series. Possible effects of asthma status are investigated. The analyses illustrate how different relationships between time series may be explored in a simple way by working on different time scales with suitably transformed variables.     

Conservative prior distributions for variance parameters in hierarchical models

Bayesian hierarchical models typically involve specifying prior distributions for one or more variance components. This is rather removed from the observed data, so specification based on expert knowledge can be difficult. While there are suggestions for “default” priors in the literature, often a conditionally conjugate inverse‐gamma specification is used, despite documented drawbacks of this choice. The authors suggest “conservative” prior distributions for variance components, which deliberately give more weight to smaller values. These are appropriate for investigators who are skeptical about the presence of variability in the second‐stage parameters (random effects) and want to particularly guard against inferring more structure than is really present. The suggested priors readily adapt to various hierarchical modelling settings, such as fitting smooth curves, modelling spatial variation and combining data from multiple sites.     

金融业分业经营、混业经营的政策辨析

在金融发展历史上,经历了多次金融分业、混业经营的循环演进。从宏观层面看,金融分业、混业是一种制度选择和制度变迁现象。金融结构的变化是多种利益博弈下的结果,市场结构、监控资源积累状况、人文因素等都影响制度结构安排和变迁路径。不同国家、地区采取不同的金融政策和金融制度是完全正常的,在金融分业与混业的制度选择上不能盲目照搬某一种模式。对分业经营、混业经营进行政策辨析,探究了混业经营成为国际金融业发展势趋的原因。     

基于混合DEA模型的医药行业上市公司经营效率相对有效性评价

DEA模型作为一种客观的多指标决策方法应用十分广泛.但目前使用频率较高的两种通用模型C²R模型和C²GS²模型,在单独使用时都有比较大的局限性,评判结果往往无法令人满意;针对这一问题,本文提出构建混合DEA模型,并应用混合DEA模型对医药上市公司的经营效率相对有效性评价进行实证分析,阐述了混合DEA模型的使用方法,验证了评判方法的可行性和科学性.     

历史、背景、法理、法律——对我国陪审制度的四维解读

陪审制度自清末移植到我国之后,经历了跌宕起伏的命运历程.由于实践中的运行不尽如人意,再加上其他一些原因,在许多学者眼里,陪审制度成了可有可无的"鸡肋",废止之声日涨.但是陪审制度有其存在的基本价值,它可以在司法独立和司法民主之间确定正常司法的位置,实现一种混合的正义.随着"人民陪审员法"的颁布和实施,陪审制度的第二个春天也许不久就会到来.     

Simultaneous Modelling of Survival and Longitudinal Data with an Application to Repeated Quality of Life Measures

In biomedical studies, interest often focuses on the relationship between patients characteristics or some risk factors and both quality of life and survival time of subjects under study. In this paper, we propose a simultaneous modelling of both quality of life and survival time using the observed covariates. Moreover, random effects are introduced into the simultaneous models to account for dependence between quality of life and survival time due to unobserved factors. EM algorithms are used to derive the point estimates for the parameters in the proposed model and profile likelihood function is used to estimate their variances. The asymptotic properties are established for our proposed estimators. Finally, simulation studies are conducted to examine the finite-sample properties of the proposed estimators and a liver transplantation data set is analyzed to illustrate our approaches.     

聚苯乙烯废料裂解初探

聚苯乙烯(PS)是一种广泛使用的塑料,使用后则产生大量废弃物。设法利用废 PS 有两方面的意义:可以再生苯乙烯单体和其他芳香烃;同时又可以减少环境污染。本文在不同条件下裂解了 PS 废料,结果得到了44.2%苯乙烯、12.9%混合芳香烃和34.5%苯乙烯齐聚体。     

中国城市商业银行推行混合所有制研究

在新一轮的国企改革中,混合所有制已成为最主要突破口,推行股东多元化与股权分散化已然是改革工作的重中之重。在商业银行这一特殊的国有控股企业中,大中型商业银行虽具有推行混合所有制的必要性,但缺少改革的可行性;相比之下,历经多次改革洗礼与监管考验的城市商业银行具备改革的必要性与可操作性,被历史性的推向改革前台。在经济新常态环境下,城市商业银行混合所有制改革要以产权结构的优化与经营机制的完善为主要抓手,坚持市场逻辑,冲破体制性障碍,在动态、持续、内在、有机融合的改革中全面提升国有资产的运行效益,走向高质量、高层次的转型发展。
